ABSTRACT
Objective To evaluate catheter thrombectomy,mechanical thromboaspiration and catheter-directed thrombolysis for the treatment of deep venous thrombosis.Methods From January 2015 to February 2016,60 patients with acute deep vein thrombosis were placed the inferior vena cava filter from contralateral femoral vein or right internal jugular vein.A 5 F pigtail catheter was led to the ipsilateral deep vein,bolus urokinase was given and catheter thrombectomy was undertaken and thromboaspiration was carried out using 10-12 F catheter,then through catheter continuous infusion of urokinase.Results 45 cases were cured,8 cases were significantly improved,5 cases were improved,2 cases were judged as ineffective,the effective rate was 96.6％.Before thrombolysis the thigh circumference difference between affected limb and the contralateral limb was (3.6 ± 1.9)cm (P ＜0.05),calf circumference difference was (4.6 ±2.1)cm (P ＜ 0.05);The difference between the affected limb and contralateral thigh circumferences was (0.19±0.90) cm (P ＞ 0.05),calf circumference difference was (0.5 ± 1.0) cm (P ＞ 0.05).Conclusions Catheter thrombectomy,thromboaspiration and catheter-directed thrombolysis for deep venous thrombosis is safe and effective.
